Abstract

The invention relates to a zoom lens with an easily bendable optical path, which comprises a reduced number of lens element while having high optical specification. The zoom lens comprises a moving lens group B (G2) that has positive refracting power and moves only toward an object side of the zoom lens upon zooming from a wide-angle end to a telephoto end of the zoom lens, a lens group A (G1) that is located on the object side with respect to the moving lens group B, has negative refracting power and remains fixed during the zooming, and a third lens group C (G3) that is located on an image side of the zoom lens with respect to the moving lens group B and moves in a locus different from that of the moving lens group B during the zooming. The lens group A that remains fixed during zooming comprises, in order from an object side thereof, a negative lens element, a reflective optical element and a positive lens element having an absolute value of refracting power smaller than that of the negative lens element. <IMAGE>
